我按照Android Developers上的说明，为我的带有导航抽屉的活动应用了沉浸式全屏。
问题是ActionBar没有隐藏。对于状态栏，文本只是消失了，而状态栏的背景颜色仍然存在。 BEFORE Before fullscreen AFTER enter image description here Code 
// This snippet hides the system bars.
    private void hideSystemUI() {
        // Set the IMMERSIVE flag.
        // Set the content to appear under the system bars so that the content
        // doesn't resize when the system bars hide and show.
        View mDecorView = getWindow().getDecorView();
        mDecorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                        | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                        | View.SYSTEM_UI_FLAG_IMMERSIVE);

        mIsActionBarVisible = false;
    }

    // This snippet shows the system bars. It does this by removing all the flags
// except for the ones that make the content appear under the system bars.
    private void showSystemUI() {
        View mDecorView = getWindow().getDecorView();
        mDecorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

        mIsActionBarVisible = true;
    }

    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
            if (hasFocus) {
                getWindow().getDecorView().setSystemUiVisibility(
                        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_IMMERSIVE);
            }
        }
    }

请问您有没有任何想法是什么出了问题？

我通过显式隐藏ActionBar来解决了这个问题：

    getSupportActionBar().hide();
